CARRIAGE OF LARGE-CALIBER GUNS FIRING FROM RAILWAY-TRACKS.

Specification of Letters Patent.

Patented Ang. 10, 1920.

Application filled June 16, 1919. Serial No. 304,649.

T0 all fr0/0m t may concern:

Be it known that I, EUGNE SCHNEIDER, a citizen of the Republic of France, residing at 42 Rue dAnjou, Paris, France, have invented new and useful Improvements in the Carriages of Large-Caliber Guns Firing from Railway-Tracks, which invention is fully set forth in the following specification.

This invention has for its object to provide various constructional forms of apparatus designed to moderate the effects of the recoil of the carriages of large-caliber guns mounted on trucks for tiring from a railway track as described in our earlier Patent No. 1,326,7881 dated Dec, 30, 1919.

In accordance with the present invention the retractable supporting devices designed to be brought into contact with the track for the purpose of braking` the recoil by sliding along the said track, are composed of elongated longitudinal sliding blocks or shoes. These longitudinal sliding blocks, instead of being brought into contact with the ordinary track rails, or with auxiliary rails, are brought into Contact with the sleepers of the permanent way.

In the recoil, the gun carriage rolls over the ordinary track rails, whereas the brake shoes when brought into Contact with the track sleepers, slide on the said sleepers to which they transmit the strains due to the firing and thereby relieve the truck wheels and axles of such forces.

This improved construction has the advantage that it does away with the necessity of providing an auxiliary slide track, without the sliding having to take place along the rails of the ordinary track.

Two constructional forms of the present invention are illustrated by way of example in the accompanying drawings in which 1 Complementary Figures 1 and ln are a side elevation of the general arrangement of a gun carriage firing from a railway track, provided with the improved apparatus for moderating the effects of the recoil.

Fig. 2 is a vertical cross section on the line Ill-II of Fig. l, drawn to a larger scale.

Complementary Figs. 3 and 32L are a diagrammatic side elevation of the general arrangement of a gun carriage embodying a modification of the improvement.

Complementary Figs. 4 and 4a are a plan view of the saine.

Complementary Figs. 5 and 5LL are a vertical ci'oss-section on the line V-V of Fig. 3, showing the shoes in raised position.

Fig. 6 is a partial section on the line VI-VI of Fig. 5.

Complementary Figs. 7 and 7 are a vertical cross-section on the line VII-VII of Fig. 4a, the same as Fig. 51 but showing the sliding shoes in the position they occupy during firing.

Referring particularly to Figs. l, l and 2, A is the carriacfe girder supported at each end on a truck r1B, C, pivoted thereto. This girder A carries permanently longitudinal slide blocks or shoes E that are adapted to be brought into and out of contact with the sleepers l on which rest the rails D of the ordinary track.

The longitudinal slide blocks or shoes E form the retractable supporting devices that are designed to slide, during the recoil, over the slideway constituted by the upper surfaces of the ordinary track sleepers cl. The shoes extend longitudinally beneath the main part of thc carriage and, having considerable length, will engage a large number of sleepers when depressed during firing. This extended engagement of the shoes with the sleeper will provide a large area of sliding contact to transmit thc forces of the gun recoil to the sleepers, the frictional contact also tending to dissipate such forces.

In this example the longitudinal slide blocks or shoes E are arranged in pairs underneath the carriage girder A in such a manner that each pair comprises between its two components one of the track rails D when the sliding shoes have been brought into contact with the sleepers d. The components E of each pair of sliding shoes are connected together at their ends by cross stays El. These cross stays El extend transversely of the carriage and are each fixed to the lower elements F, Gr, of a screw jack similar to those described in our aforesaid earlier patent, and the complementary elements H, I of the screw jacks are carried by the gun carriage girder.

By operating these screw jacks by means of the actuating mechanisms M-L-K the screws I are caused to revolve on their axes so as to raise or lower the nuts Cr, and thereby correspondingly move the cross stays El and the sliding shoes E carried by the latter.

Figs. 3 to 7 illustrate a modification wherein the retractable'devices consist of two sliding shoes E which, instead of being fixed to connecting cross stays El carried by the lower elements F, G of the supporting screw jacks, are removably or adjustably attached to the said cross stays by means that permit the shifting ot the sliding shoes parallelly to their own longitudinal axes. In this instance the cross stays El extend entirely across the carriage. In this way the sliding shoes can be attached to varying points of the length of the connecting` cross stays in such a manner as that one or the other of the longitudinal sliding blocks or shoes shall be capable of being attached at will in a vertical plane passing between the two track rails or in a plane intersecting the arc formed by the inside rail, according to the position of the center o1c curvature of the firing track.

The longitudinal sliding blocks E are attached, for transport, to connecting cross stays El which serve during the tiring, as parts for drawing the sliding shoes along in the longitudinal direction, by means of angle bars e fixed to the said shoes and engaging opposite sides of the cross stays.

For transport, the sliding 'shoes E are suspended by their upper flanges from hooks Y. These hook jaws are formed each on a nut working on a screw-thread (oil the requisite hand) of a spindle y. The nuts Y are slidable in a carriage Z which is lixed to a screw .e working at one end in a screwthread l formed in a bar 2 having a guideway wherein the carriage Z is adapted to slide. The hook jaws Y are slidable in the carriage Z, and the spindle y is journaled at its ends in the carriage Z.

lVhen the sliding shoes E are suspended for transport as shown in Figs. 5 and 6, it is possible by operating the screw e by means of the crank handle el, to move the right hand sliding shoe in such a manne-r as to bring it into a suitable plane. lThe screw e moves longitudinally in the fixed bar 2, and in rotating in the nut 1 it moves the sliding` shoes E along by means ot the jaw Y.

When the sliding shoes have been moved into the desired vertical plane, they can be brought into contact with the sleepers l by operating the screw jacks F-Gr-H-h-I.

lt it be desired to abandon the sliding shoes E on the spot, for maneuvering purposes or for any other reason. it will be sufficient to that end, to move the jaws Y apart and then raise the cross stays E1. This moving apart of the jaws Y is effected by actuating the crank handle g/l in the requisite direction.

After the liring is ended, the whole coinbination of the sliding shoes E and connecting cross stays El is raised by 'suitably operating the screw jacks F-Gr-H-I, and

then the right hand sliding shoe is moved back inward by actuating the respective crank handle el.

The position of the sliding shoes E shown in Fig. 7 is suitable for liring from the curved track shown in full lines in Figs. t-tf". The carriage is supported by wheeled trucks pivoted to the under side of its ends and these trucks must necessarily follow the supporting rails during the travel of the carriage. Vith the carriage situated on a curved track the pivotal connections between theI carriage and trucks coincide with the medial curved line of the supporting rails, but the rigid carriage forms the chord of an arc in the medial line, the altitude of the arc depending on the length of the radius of the curve. With the carriage s0 placed, particularly if the curve of the rails should be made with a comparatively short radius, the longitudinal shoes E should be positioned to engage the sleepers on the inner side of the curvature of the rails, as shown in full lines in Figs. fel-L1 and in Fig. 7. So positioned the shoes would be. more nearly directly below the gun than if positioned to engage the sleepers on the outer side of the curve. l,Vith a curve made with a comparatively long radius the shoes could be adjusted to either side of the rails as in a straight track.

lVhen it is desired to iire from a track having its center oi' curvature on the opposite side, it is advisable to cause the two sliding shoes E to slide in such a manner as to bring them into the position indicated in dot and dash lines in Fig. 4. This sliding is produced by actuating the crank handle .el in the requisite direction.
